1.1 This is a practice for using radiochromic film dosimetry
systems to measure absorbed dose in materials irradiated by
photons or electrons in terms of absorbed dose to water.
Radiochromic film dosimetry systems are generally used as
routine dosimetry systems.
1.2 The radiochromic film dosimeter is classified as a Type
II dosimeter on the basis of the complex effect of influence
quantities. See ASTM Practice E2628.
1.3 This document is one of a set of standards that provides
recommendations for properly implementing dosimetry in
radiation processing, and describes a means of achieving
compliance with the requirements of ASTM E2628 “Practice
for Dosimetry in Radiation Processing” for a radiochromic film
dosimetry system. It is intended to be read in conjunction with
ASTM E2628.
1.4 This practice covers the use of radiochromic film
dosimetry systems under the following conditions:
1.4.1 The absorbed dose range is 1 Gy to 150 kGy.
1.4.2 The absorbed dose rate is 1 3 10-2 to 1 3 1013
Gy·s-1 (1-4).2
1.4.3 The photon energy range is 0.1 to 50 MeV.
1.4.4 The electron energy range is 70 keV to 50 MeV.
1.5 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability
of regulatory limitations prior to use.
